Starship Asterisk*

If supernovas trigger star formation, Gum wasn’t our mother.

Which one was is shaping new science.

Bending light produces mind-bending opportunities. From Terrascopes to gravity scopes.

The possibilities are supernumerary!

Beautiful Saturn! Will Dragonfly solve some of Titans mysteries?

Possibly Orin and this may be one of them.

I couldn't even find it in " Molecule of the Week"

Zooming in, we see a galaxy similar to our own but with some distinct differences.

I wonder if the cloudy sections in the core would resemble the nebulas - making ours "milky"

Beautiful complexity. Torus structure in the life and death of stars seems to tell us something about the universe.

Close, but no cigar on Oumuamua update.

Am I the only one who doesn't know what the dashed line near the horizon on the right is being caused by? Also, as usual, I'm confused about the imaging process described. Was only one of the exposures used to capture the moon, or was the moon tracked by the camera and part of each of the 16 exposu...

The other night Mars was much closer to the moon. But all the same players were in the vicinity.

Thank you Chris! I like the way you presented the phases from your neck of the woods.

Methods have been thought of to clean solar panels but perhaps a really strong mars quake could do the trick.

What a coincidence.

Does
asteroid detection data that includes the orbits of other planets for impacts?

Are the short line segments reflected in the water stars or something else? But if stars, I would have expected them to look like points not lines, like in this old APOD - https://apod.nasa.gov/apod/ap140916.html The water surface must have been a little bit in motion relative to the camera. In mot...

For the records, let's hope they only arrive from beyond.

There are other choices.

Let alone, all the people.

Of course!!!! Triton is brighter than Neptune in the infrared picture by Webb for exactly the same reason why it looks bluish in visible light: It is because methane in Neptune's atmosphere absorbs and dims infrared light detected by the Webb telescope, at the same time making Neptune bluish at opt...

I'll never look that comfortable on a horse but once you get on top, the view's not bad. After a bit more hiking.

Just got back from Idaho’s Challis National Forrest’s White Cloud – Boulder Chain Lakes area. Like today’s APOD we found an eagle too. I have a newfound respect for people who ride horses – a second time.

Oh yeah, it's Perseid shower time this weekend! Thanks for reminding me. As I grow older the calendar dates seem to swarm together in a meaningless mob. Another day just like thousands of others come before. By the way, I presume the meteors are the long streaks and the gamma rays are the sparkling...

Something about hummingbirds make them photogenic. Maybe because I'm jealous of their metabolism.

The moon with accessories often make for fun photos.

Of all the ways to enjoy our closest nieghbor, I might pick augmented virtual reality.

All the fun without the muss. A highway without the danger zone.

Probably some shadow like illustrated on the Cassini Imaging Team link.

Constraints of early matter formation are being investigated too.
